I have wireless carplay in my wifes X3. I think BMW is one of the only car manufacturers to currently offer carplay wireless (non tethered) natively from the manufacturer. With that being said, I dont like carplay in general, so in her car we use the BMW iDrive interface, mostly because we are used to it after close to 15 years of being "team bmw".
In BMWs implementation, its not much different than wired carplay, just that you have to buy the feature (cause BMW makes you buy a bunch of packages, not as bad as porsche but close). Wireless carplay on her X3 came with purchasing the integrated wireless charging, which I wanted.
Anyway, it works ok in there if you like carplay but I prefer iDrive on BMWs interface so we dont use carplay there.
